If you look at the pcap, however:

dragorn@drd1812 ~/wavehack/ubm $ tcpdump -r foo.pcap
reading from file foo.pcap, link-type EN10MB (Ethernet)

it's definitely not from a monitor mode wifi device.

Are you using the latest version of kismet? What drivers are you using? Kismet should absolutely be making a monitor mode VAP.

Were you missing libnl when kismet was built?

ERROR: Source 'wlan0' doesn't have mac80211 support, disabling VAP
creation of default monitor mode VAP

implies that you were - a mac80211 device is going to behave awfully badly if you don't have libnl; I imagine it's not properly setting mode since a vap can't be mode-changed in mac80211, you're supposed to make a new VAP via nl.

If you really can't easily recompile kismet with proper netlink support, a hack would be to make a vap manually with iw:

iw wlan0 interface add wlan0mon type monitor

and then point Kismet at that.

I'm adding more explicit checks to Kismet now to detect this situation and punt more explicit errors.
